Hugh MacDiarmid’s Poetics of Commitment: the Modern Stigmata of Bereavement
2016
In the 1930s, the lingering absence of God and of a stable reality engulfed the work of the poet Hugh MacDiarmid, leader of the Scottish Renaissance Movement. To counter this void, like many others at the time, MacDiarmid found refuge in communism and nationalism and started to write political and idealist poetry. In his poems, his political idealism comes into being in the association of reality and ideal, symbolised first by Jean and Sophia, the characters of A Drunk Man Looks at the Thistle (1926), and duplicated later in the fantasised image of Lenin, perfect blending of idea and action. Rejecting Sartre’s denial of the political effect poetry can have, the violence of MacDiarmid’s work…
Modèle global et paramétrable, pour la gestion des foules d'agents en animation comportementale
2011
The realism of crowd behavioral animation is based on one hand on a rendering of graphic scenes generated by the application, and on the other hand on the realism of the behavior. This is last point which is our object of study. The realism of crowds' behavior is essentially global (macroscopic realism). It must respect the required statistical characteristics of the crowd (density, dispersal, speed…) similar to those of a real crowd. The realism is also local (microscopic realism), i.e. agents should ideally behave like humans or human groups taken as reference, at least in the focus of the considered application. The aim of our research is to propose a generic model to perform crowd behav…
Study of acoustic properties and impact behavior of porous materials homogeneous type metal foams and inhomogeneous
2015
This work is concerned with the theoretical and experimental study of the acoustical properties of macroscopically homogenous and inhomogeneous porous media as well as their mechanical response to impacts. The model of Johnson - Champoux - Allard appeared adapted for the acoustical modeling. This model, associated with a recently developed approach involving the concept of parallel transfer matrices has lead to a new approach of macroscopically inhomogeneous porous materials based on “mixtures of materials”. Furthermore, a parametric study of the absorption coefficient as a function of porosity and frequency has been proposed. The maximums of absorption as well as the envelop of the absorpt…
Inoculación de estrés en la adolescencia: atenuación de los efectos reforzantes y motivacionales del etanol inducido por estrés social en ratones mac…
2021
Numerosos estudios han demostrado que la exposición a estrés social está relacionada con un mayor riesgo a desarrollar un trastorno por abuso de sustancias. Las experiencias estresantes durante la adolescencia pueden afectar al desarrollo del cerebro, ejerciendo así una influencia profunda y duradera en el desarrollo mental y la salud psicológica. Existe una hipótesis relacionada con la exposición al estrés en etapas tempranas de la vida que presupone que los individuos que han experimentado un estrés de moderada o baja intensidad, pueden adquirir cierta resistencia a exposiciones más profundas en la adultez. En este estudio nos propusimos estudiar esta hipótesis como una forma de potenciar…
Harmonic Balance Method and Stability of Discontinuous Systems
2019
The development of the theory of discontinuous dynamical systems and differential inclusions was not only due to research in the field of abstract mathematics but also a result of studies of particular problems in mechanics. One of first methods, used for the analysis of dynamics in discontinuous mechanical systems, was the harmonic balance method developed in the thirties of the 20th century. In our work the results of analysis obtained by the method of harmonic balance, which is an approximate method, are compared with the results obtained by rigorous mathematical methods and numerical simulation. peerReviewed
Effects of the air density value on a wind generator electricity production capability
2016
The paper main issue is the evaluation of the influence of the air density value on the electricity production capability of a wind generator. Two different density air mathematical models, where the density has not a constant value, are here taken into account and compared in terms of reliability, accuracy and computational burden. Evaluations are carried out thanks to a horizontal axis wind generator full model built by the Authors in Matlab/Simulink environment. Simulation results are compared with real data.
On the occurrence of Eudiaptomus gracilis (G.O. Sars, 1863) (Copepoda: Diaptomidae) in Madeira (Portugal)
2020
Calanoid copepods belonging to the diaptomid genus Eudiaptomus Kiefer, 1932 were collected in an artificial water body on the island of Madeira, Portugal. The morphological and molecular identification of the collected specimens unequivocally proved that they belong to the allochthonous species Eudiaptomus gracilis (G. O. Sars, 1863), possibly unwarily introduced along with fish stockings or ornamental aquatic plants. In the sampled site, the species co-occurred with the non-native cyclopoid copepod Acanthocyclops americanus (Marsh, 1893) and some anomopod species. This is the first record of the species for Portugal and the whole Macaronesia, whereas the possible presence of E. gracilis in…
STUDIO NUMERICO-SPERIMENTALE DI GIUNZIONI IBRIDE A DOPPIA SOVRAPPOSIZIONE CFRP-ALLUMINIO
2013
The adhesively bonded joints and the mechanical joints between structural components made by composite materials or between elements made by composite and metal, are commonly used in different fields of modern industrial design and manufacturing, since they are characterized by economy, reliability and ease of assembly. The bonded joints are characterized by high stiffness and fatigue life, although delamination phenomena localized near the edges of attack of the adherends may limit their use, especially in particular applications where corrosive environments and humidity can lead to premature failure. In these cases, a possible alternative is offered by the well known riveted joints. On th…
Eelness: Transcriptomic analysis of Vibrio-induced immune response in European eel
2014
La malaltia és l’alteració de l’estat fisiològic d’un individu, dificultant les seves funcions vitals i fins i tot, comportant a la mort. Tots els éssers vius poden contraure malaltia, aquesta, és majoritàriament provocada per microorganismes patògens, incloent bacteris, virus, protozous i fongs. Al llarg de la infecció, la relació hoste-patògen és clau. Per una banda, l’hoste ha de comptar amb un sistema immunitari eficaç, capaç de combatre l’infecció, mantenint les funcions vitals i per tant, evitant la mort. Per l’altre banda, el patogen desenvolupa una sèrie de factors per tal de aconseguir una invasió exitosa i per tant, provocant infecció. L’objectiu principal d’aquest tesi és l’estud…
A novel pilot study of automatic identification of EMF radiation effect on brain using computer vision and machine learning
2020
Abstract Electromagnetic field (EMF) radiations from mobile phones and cell tower affect brain of humans and other organisms in many ways. Exposure to EMF could lead to neurological changes causing morphological or chemical changes in the brain and other internal organs. Cellular level analysis to measure and identify the effect of mobile radiations is an expensive and long process as it requires preparing the cell suspension for the analysis. This paper presents a novel pilot study to identify changes in brain morphology under EMF exposure considering drosophila melanogaster as a specimen. The brain is automatically segmented, obtaining microscopic images from which discriminatory geometri…
